1. IntroductionCreader 529 OBD II Scanner is developed by
LAUNCH, especially for the DIY users and the servicemen of small
service workshop. It supports read/clear DTCs and read data stream.
With built-in help menus and code definitions, diagnosing and
repairing that dreaded Check Engine Light is now easier than
ever!It provides the ability to print the diagnostic records
through connection to PC.Moreover, it can be connected to PC
through the USB cable for upgrade to keep updated with the latest
software version.
Note: This scanner may automatically reset while being disturbed
by strong static electricity. THIS IS A NORMAL REACTION.
This scanner is specially designed to work with all OBD II
compliant vehicles, including Controller Area Network (CAN). It is
required by EPA that all 1996 and newer vehicles (cars and light
trucks) sold in the United States must be OBD II compliant and this
includes all American, Asian and European vehicles.A small number
of 1994 and 1995 model year gasoline vehicles are OBD II compliant.
To verify if a 1994 or 1995 vehicle is OBD II compliant, check the
following:1. Vehicle Emissions Control Information (VECI) Label. It
is located
under the hood or by the radiator of most vehicles. If the
vehicle is OBD II compliant, the label will designate “OBD II
Certified”.
2. Government regulations mandate that all OBD II compliant
vehicles must have a “common” 16-pin Data Link Connector (DLC).

Note: Some 1994 and 1995 vehicles have 16-pin connectors but are
not OBD II compliant. Only those vehicles with a Vehicle Emissions
Control Label stating “OBD II Certified” are OBD II compliant.

2. General Information-About OBDII/EOBD
2.1 On-Board Diagnostics (OBD) I
Note: With the exception of some 1994 and 1995 vehicles, most
vehicles from 1982 to 1995 are equipped with some type of first
generation On-Board Diagnostics.
Beginning in 1988, California’s Air Resources Board (CARB), and
later the Environmental Protection Agency (EPA) required vehicle
manufacturers to include a self-diagnostic program in their
on-board computers. The program would be capable of identifying
emissions-related faults in a system. The first generation of
Onboard Diagnostics came to be known as OBD I.OBD I is a set of
self-testing and diagnostic instructions programmed into the
vehicle’s onboard computer. The programs are specifically designed
to detect failures in the sensors, actuators, switches and wiring
of the various vehicle emissions-related systems. If the computer
detects a failure in any of these components or systems, it lights
an indicator on the dashboard to alert the driver. The indicator
lights only when an emissions-related problem is detected.The
computer also assigns a numeric code for each specific problem that
it detects, and stores these codes in its memory for later
retrieval. These codes can be retrieved from the computer’s memory
with the use of a “Code Reader” or a “Diagnostic Tool.”
2.2 On-Board Diagnostics (OBD) IIAs technology evolved and the
desire to improve the On-Board Diagnostic system increased, a new
generation of On-Board Diagnostic system was developed. This second
generation of On-Board Diagnostic regulations is called “OBD II”.
In addition to performing all the functions of the OBD I System,
the OBD II System has been enhanced with new Diagnostic Programs.
These programs closely monitor the functions of various
emissions-related components and systems (as well as other systems)
and make this information readily available (with the proper
equipment) to the technician for evaluation.The California Air
Resources Board (CARB) conducted studies on OBD I equipped
vehicles. The information that was gathered from these studies
-
4
LAUNCH 529 OBD II Scanner User’s Manual
showed the following:• A large number of vehicles had
deteriorating or degraded emissions-related
components. These components were causing an increase in
emissions.• Because OBD I systems only detect failed components,
the degraded
components were not setting codes.• Some emissions problems
related to degraded components only occur
when the vehicle is being driven under a load. The emission
checks being conducted at the time were not performed under
simulated driving conditions. As a result, a significant number of
vehicles with degraded components were passing Emissions Tests.
• Codes, code definitions, diagnostic connectors, communication
protocols and emissions terminology were different for each
manufacturer. This caused confusion for the technicians working on
different make and model vehicles.
To address the problems made evident by this study, CARB and the
EPA passed new laws and standardization requirements. These laws
required that vehicle manufacturers to equip their new vehicles
with devices capable of meeting all of the new emissions standards
and regulations. It was also decided that an enhanced on-board
diagnostic system, capable of addressing all of these problems, was
needed. This new system is known as “On-Board Diagnostics
Generation Two (OBD II).” The primary objective of the OBD II
system is to comply with the latest regulations and emissions
standards established by CARB and the EPA.The Main Objectives of
the OBD II System are:• To detect degraded and/or failed
emissions-related components or systems
that could cause tailpipe emissions to exceed by 1.5 times the
Federal Test Procedure (FTP) standard.
• To expand emissions-related system monitoring. This includes a
set of computer run diagnostics called Monitors. Monitors perform
diagnostics and testing to verify that all emissions-related
components and/or systems are operating correctly and within the
manufacturer’s specifications.
• To use a standardized Diagnostic Link Connector (DLC) in all
vehicles. (Before OBD II, DLCs were of different shapes and
sizes.)
• To standardize the code numbers, code definitions and language
used to describe faults. (Before OBD II, each vehicle manufacturer
used their own code numbers, code definitions and language to
describe the same faults.)
• To expand the operation of the Malfunction Indicator Lamp
(MIL).
-
LAUNCH 529 OBD II Scanner User’s Manual

• To standardize communication procedures and protocols between
the diagnostic equipment (Diagnostic Tools, Code Readers, etc.) and
the vehicle’s on-board computer.
2.3 Diagnostic Trouble Codes (DTCs)OBD II Diagnostic Trouble
Codes are codes that are stored by the on-board computer diagnostic
system in response to a problem found in the vehicle. These codes
identify a particular problem area and are intended to provide you
with a guide as to where a fault might be occurring within a
vehicle. DO NOT replace parts based only on DTCs without first
consulting the vehicle’s service manual for proper testing
procedures for that particular system, circuit or component. OBD II
Diagnostic Trouble Codes consist of a five-digit alphanumeric code.
• The 1st character is a letter (B, C, P or U). It identifies the
“main system”
where the fault occurred (Body, Chassis, Powertrain, or
Network).• The 2nd character is a numeric digit (0 thru 3). It
identifies the “type” of
code (Generic or Manufacturer-Specific).
Note: Generic DTCs are codes that are used by all vehicle
manufacturers. The standards for generic DTCs, as well as their
definitions, are set by the Society of Automotive Engineers
(SAE).Manufacturer-Specific DTCs are codes that are controlled by
the vehicle manufacturers. The Federal Government does not require
vehicle manufacturers to go beyond the standardized generic DTCs in
order to comply with the new OBD II emissions standards. However,
manufacturers are free to expand beyond the standardized codes to
make their systems easier to diagnose.
• The 3rd character is a letter or a numeric digit (0 thru 9, A
thru F). It identifies the specific system or sub-system where the
problem is located.
• The 4th and 5th characters are letters or numeric digits (0
thru 9, A thru F). They identify the section of the system that is
malfunctioning.

2.4 Location of the Data Link Connector (DLC)The DLC (Data Link
Connector or Diagnostic Link Connector) is the standardized
16-cavity connector where diagnostic code readers interface with
the vehicle’s on-board computer. The DLC is usually located 12
inches from

the center of the instrument panel (dash), under or around the
driver’s side for most vehicles. If Data Link Connector is not
located under dashboard, a label should be there telling location.
For some Asian and European vehicles, the DLC is located behind the
ashtray and the ashtray must be removed to access the connector. If
the DLC cannot be found, refer to the vehicle’s service manual for
the location.
2.5 OBD II TerminologyThe following terms and their definitions
are related to OBD II systems. Read and reference this list as
needed to aid in the understanding of OBD II systems.
Powertrain Control Module (PCM) -- The PCM is the OBD II
accepted term for the vehicle’s “on-board computer.” In addition to
controlling the engine management and emissions systems, the PCM
also participates in controlling the powertrain (transmission)
operation. Most PCMs also have the ability to communicate with
other computers on the vehicle (ABS, ride control, body, etc.).
Monitors -- Monitors are “diagnostic routines” programmed into
the PCM. The PCM utilizes these programs to run diagnostic tests,
and to monitor operation of the vehicle’s emissions-related
components or systems to ensure they are operating correctly and
within the vehicle’s manufacturer specifications. Currently, up to
fifteen Monitors are used in OBD II systems. Additional Monitors
will be added as the OBD II system is further developed.
Note: Not all vehicles support all fifteen Monitors.
-
8
LAUNCH 529 OBD II Scanner User’s Manual
Enabling Criteria -- Also termed Enabling Conditions. They are
the vehicle-specific events or conditions that must occur within
the engine before the various monitors will set, or run. Some
monitors require the vehicle to follow a prescribed “drive cycle”
routine as part of the enabling criteria. Drive cycles vary among
vehicles and for each monitor in any particular vehicle. Please
refer to the vehicle’s factory service manual for specific enabling
procedures.
Trip - A Trip for a particular Monitor requires that the vehicle
is being driven in such a way that all the required “Enabling
Criteria” for the Monitor to run and complete its diagnostic
testing are met. The “Trip Drive Cycle” for a particular Monitor
begins when the ignition key is turned “On.” It is successfully
completed when all the “Enabling Criteria” for the Monitor to run
and complete its diagnostic testing are met by the time the
ignition key is turned “Off.” Since each of the fifteen monitors is
designed to run diagnostics and testing on a different part of the
engine or emissions system, the “Trip Drive Cycle” needed for each
individual Monitor to run and complete varies.
OBD II Drive Cycle -- A specific mode of vehicle operation that
provides conditions required to set all the readiness monitors
applicable to the vehicle to the “ready” condition. The purpose of
completing an OBD II drive cycle is to force the vehicle to run its
onboard diagnostics. Some form of a drive cycle needs to be
performed after DTCs have been erased from the PCM’s memory or
after the battery has been disconnected. Running through a
vehicle’s complete drive cycle will “set” the readiness monitors so
that future faults can be detected. Drive cycles vary depending on
the vehicle and the monitor that needs to be reset. For vehicle
specific drive cycle, consult the service manual.
Note: Do not confuse a “Trip” Drive Cycle with an OBD II Drive
Cycle. A “Trip” Drive Cycle provides the “Enabling Criteria” for
one specific Monitor to run and complete its diagnostic testing. An
OBD II Drive Cycle must meet the “Enabling Criteria” for all
Monitors on a particular vehicle to run and complete their
diagnostic testing.
Warm-up Cycle - Vehicle operation after an engine off period
where engine temperature rises at least 40°F (22°C) from its
temperature before starting, and reaches at least 160°F (70°C). The
PCM uses warm-up cycles as a counter to automatically erase a
specific code and related data from its memory. When no faults
related to the original problem are detected within a specified
number of warm-up cycles, the code is erased automatically.
Fuel Trim (FT) - Feedback adjustments to the base fuel schedule.
Short-term fuel trim refers to dynamic or instantaneous
adjustments. Long-term fuel trim
-
LAUNCH 529 OBD II Scanner User’s Manual
9
refers to much more gradual adjustments to the fuel calibration
schedule than short-term trim adjustments. These long-term
adjustments compensate for vehicle differences and gradual changes
that occur over time.
2.6 OBD II MonitorsAn important part of a vehicle’s OBD II
system is the Readiness Monitors, which are indicators used to find
out if all of the emissions components have been evaluated by the
OBD II system. They are running periodic tests on specific systems
and components to ensure that they are performing within allowable
limits.Monitor operation is either “Continuous” or
“Non-Continuous,” depending on the specific monitor.
2.6.1 Continuous MonitorsSome of the vehicle components or
systems are continuously tested by the vehicle’s OBD II system,
while others are tested only under specific vehicle operating
conditions. The continuously monitored components listed below are
always ready:
1. Misfire MonitorThis Monitor continuously checks for engine
misfires. A misfire occurs when the air-fuel mixture in the
cylinder does not ignite. The misfire Monitor uses changes in
crankshaft speed to sense an engine misfire. When a cylinder
misfires, it no longer contributes to the speed of the engine, and
engine speed decreases each time the affected cylinder(s) misfire.
The misfire Monitor is designed to sense engine speed fluctuations
and determine from which cylinder(s) the misfire is coming, as well
as how bad the misfire is.There are three types of engine misfires,
Types 1, 2, and 3.• Type 1 and Type 3 misfires are two-trip monitor
faults. If a fault is sensed
on the first trip, the computer temporarily saves the fault in
its memory as a Pending Code. The MIL is not commanded on at this
time. If the fault is found again on the second trip, under similar
conditions of engine speed, load and temperature, the computer
commands the MIL “On,” and the code is saved in its long term
memory.
• Type 2 misfires are the most severe type of misfire. When a
Type 2 misfire is sensed on the first trip, the computer commands
the MIL to light when the misfire is sensed. If the computer
determines that a Type 2 misfire is severe, and may cause catalytic
converter damage, it commands the MIL
-
10
LAUNCH 529 OBD II Scanner User’s Manual
to “flash” once per second as soon as the misfire is sensed.
When the misfire is no longer present, the MIL reverts to steady
“On” condition.
The Misfire Monitor is supported by both “spark ignition”
vehicles and “compression ignition” vehicles.
2. Fuel System MonitorThis Monitor uses a Fuel System Correction
program, called Fuel Trim, inside the on-board computer. Fuel Trim
is a set of positive and negative values that represent adding or
subtracting fuel from the engine. This program is used to correct
for a lean (too much air/not enough fuel) or rich (too much
fuel/not enough air) air-fuel mixture. The program is designed to
add or subtract fuel, as needed, up to a certain percent. If the
correction needed is too large and exceeds the time and percent
allowed by the program, a fault is indicated by the computer.The
Fuel System Monitor is supported by both “spark ignition” vehicles
and “compression ignition” vehicles. The Fuel System Monitor may be
a “One-Trip” or “Two-Trip” Monitor, depending on the severity of
the problem.
3. Comprehensive Components Monitor (CCM) This Monitor
continuously checks all inputs and outputs from sensors, actuators,
switches and other devices that provide a signal to the computer.
The Monitor checks for shorts, opens, out of range value,
functionality and “rationality* (See Note).”
Rationality: Each input signal is compared against all other
inputs and against information in the computer’s memory to see if
it makes sense under the current operating conditions. Example: The
signal from the throttle position sensor indicates the vehicle is
in a wide-open throttle condition, but the vehicle is really at
idle, and the idle condition is confirmed by the signals from all
other sensors. Based on the input data, the computer determines
that the signal from the throttle position sensor is not rational
(does not make sense when compared to the other inputs). In this
case, the signal would fail the rationality test.
The CCM is supported by both “spark ignition” vehicles and
“compression ignition” vehicles. The CCM may be either a “One-Trip”
or a “Two-Trip” Monitor, depending on the component.

2.6.2 Non-Continuous Monitors“Non-continuous” Monitors perform
and complete their testing once per trip. The “non-continuous”
Monitors are:
1. O2 Sensor MonitorThe Oxygen Sensor monitors how much oxygen
is in the vehicle’s exhaust. It generates a varying voltage of up
to one volt, based on how much oxygen is in the exhaust gas, and
sends the signal to the computer. The computer uses this signal to
make corrections to the air/fuel mixture. If the exhaust gas has a
large amount of oxygen (a lean air/fuel mixture), the oxygen sensor
generates a “low” voltage signal. If the exhaust gas has very
little oxygen (a rich mixture condition), the oxygen sensor
generates a “high” voltage signal. A 450mV signal indicates the
most efficient, and least polluting, air/fuel ratio of 14.7 parts
of air to one part of fuel.The oxygen sensor must reach a
temperature of at least 600-650°F, and the engine must reach normal
operating temperature, for the computer to enter into closed-loop
operation.The oxygen sensor only functions when the computer is in
closed-loop. A properly operating oxygen sensor reacts quickly to
any change in oxygen content in the exhaust stream. A faulty oxygen
sensor reacts slowly, or its voltage signal is weak or missing.The
Oxygen Sensor Monitor is supported by “spark ignition” vehicles
only. The Oxygen Sensor Monitor is a “Two-Trip” monitor. If a fault
is found on the first trip, the computer temporarily saves the
fault in its memory as a Pending Code. The computer does not
command the MIL on at this time. If the fault is sensed again on
the second trip, the computer commands the MIL “On,” and saves the
code in its long-term memory.
2. O2 Sensor Heater MonitorThe Oxygen Sensor Heater Monitor
tests the operation of the oxygen sensor’s heater. There are two
modes of operation on a computer-controlled vehicle: “open-loop”
and “closed-loop.” The vehicle operates in open-loop when the
engine is cold, before it reaches normal operating temperature. The
vehicle also goes to open-loop mode at other times, such as heavy
load and full throttle conditions. When the vehicle is running in
open-loop, the oxygen sensor signal is ignored by the computer for
air/fuel mixture corrections. Engine efficiency during open-loop
operation is very low, and results in the production of more
vehicle emissions.Closed-loop operation is the best condition for
both vehicle emissions and
-
12
LAUNCH 529 OBD II Scanner User’s Manual
vehicle operation. When the vehicle is operating in closed-loop,
the computer uses the oxygen sensor signal for air/fuel mixture
corrections.In order for the computer to enter closed-loop
operation, the oxygen sensor must reach a temperature of at least
600°F. The oxygen sensor heater helps the oxygen sensor reach and
maintain its minimum operating temperature (600°F) more quickly, to
bring the vehicle into closed-loop operation as soon as
possible.The Oxygen Sensor Heater Monitor is supported by “spark
ignition” vehicles only. The Oxygen Sensor Heater Monitor is a
“Two-Trip” Monitor. If a fault is found on the first trip, the
computer temporarily saves the fault in its memory as a Pending
Code. The computer does not command the MIL on at this time. If the
fault is sensed again on the second trip, the computer commands the
MIL “On,” and saves the code in its long-term memory.
3. Catalyst MonitorThe catalytic converter is a device that is
installed downstream of the exhaust manifold. It helps to oxidize
(burn) the unburned fuel (hydrocarbons) and partially burned fuel
(carbon monoxide) left over from the combustion process. To
accomplish this, heat and catalyst materials inside the converter
react with the exhaust gases to burn the remaining fuel. Some
materials inside the catalytic converter also have the ability to
store oxygen, and release it as needed to oxidize hydrocarbons and
carbon monoxide. In the process, it reduces vehicle emissions by
converting the polluting gases into carbon dioxide and water.The
computer checks the efficiency of the catalytic converter by
monitoring the oxygen sensors used by the system. One sensor is
located before (upstream of) the converter; the other is located
after (downstream of) the converter. If the catalytic converter
loses its ability to store oxygen, the downstream sensor signal
voltage becomes almost the same as the upstream sensor signal. In
this case, the monitor fails the test.The Catalyst Monitor is
supported by “spark ignition” vehicles only. The Catalyst Monitor
is a “Two-Trip” Monitor. If a fault is found on the first trip, the
computer temporarily saves the fault in its memory as a Pending
Code. The computer does not command the MIL on at this time. If the
fault is sensed again on the second trip, the computer commands the
MIL “On” and saves the code in its long-term memory.
4. Heated Catalyst MonitorOperation of the “heated” catalytic
converter is similar to the catalytic
-
LAUNCH 529 OBD II Scanner User’s Manual
13
converter. The main difference is that a heater is added to
bring the catalytic converter to its operating temperature more
quickly. This helps reduce emissions by reducing the converter’s
down time when the engine is cold. The Heated Catalyst Monitor
performs the same diagnostic tests as the catalyst Monitor, and
also tests the catalytic converter’s heater for proper
operation.The Heated Catalyst Monitor is supported by “spark
ignition” vehicles only. This Monitor is also a “Two-Trip”
Monitor.
5. EGR (Exhaust Gas Recirculation) System MonitorThe Exhaust Gas
Recirculation (EGR) system helps reduce the formation of Oxides of
Nitrogen during combustion. Temperatures above 2500°F cause
nitrogen and oxygen to combine and form Oxides of Nitrogen in the
combustion chamber. To reduce the formation of Oxides of Nitrogen,
combustion temperatures must be kept below 2500°F. The EGR system
recirculates small amounts of exhaust gas back into the intake
manifold, where it is mixed with the incoming air/fuel mixture.
This reduces combustion temperatures by up to 500°F. The computer
determines when, for how long, and how much exhaust gas is
recirculated back to the intake manifold. The EGR Monitor performs
EGR system function tests at preset times during vehicle
operation.The EGR Monitor is supported by both “spark ignition”
vehicles and “compression ignition” vehicles. The EGR Monitor is a
“Two-Trip” Monitor. If a fault is found on the first trip, the
computer temporarily saves the fault in its memory as a Pending
Code. The computer does not command the MIL on at this time. If the
fault is sensed again on the second trip, the computer commands the
MIL “On,” and saves the code in its long-term memory.
6. EVAP System MonitorOBD II vehicles are equipped with a fuel
Evaporative system (EVAP) that helps prevent fuel vapors from
evaporating into the air. The EVAP system carries fumes from the
fuel tank to the engine where they are burned during combustion.
The EVAP system may consist of a charcoal canister, fuel tank cap,
purge solenoid, vent solenoid, flow monitor, leak detector and
connecting tubes, lines and hoses.Fumes are carried from the fuel
tank to the charcoal canister by hoses or tubes. The fumes are
stored in the charcoal canister. The computer controls the flow of
fuel vapors from the charcoal canister to the engine via a purge
solenoid. The computer energizes or deenergizes the purge solenoid
(depending on solenoid design). The purge solenoid opens a valve to
allow
-
14
LAUNCH 529 OBD II Scanner User’s Manual
engine vacuum to draw the fuel vapors from the canister into the
engine where the vapors are burned. The EVAP Monitor checks for
proper fuel vapor flow to the engine, and pressurizes the system to
test for leaks. The computer runs this Monitor once per trip.The
EVAP Monitor is supported by “spark ignition” vehicles only. The
EVAP Monitor is a “Two-Trip” Monitor. If a fault is found on the
first trip, the computer temporarily saves the fault in its memory
as a Pending Code. The computer does not command the MIL on at this
time. If the fault is sensed again on the second trip, the PCM
commands the MIL “On,” and saves the code in its long-term
memory.
7. Secondary Air System MonitorWhen a cold engine is first
started, it runs in open-loop mode. During open-loop operation, the
engine usually runs rich. A vehicle running rich wastes fuel and
creates increased emissions, such as carbon monoxide and some
hydrocarbons. A Secondary Air System injects air into the exhaust
stream to aid catalytic converter operation:• It supplies the
catalytic converter with the oxygen it needs to oxidize the
carbon monoxide and hydrocarbons left over from the combustion
process during engine warmup.
• The extra oxygen injected into the exhaust stream also helps
the catalytic converter reach operating temperature more quickly
during warm-up periods. The catalytic converter must heat to
operating temperature to work properly.
The Secondary Air System Monitor checks for component integrity
and system operation, and tests for faults in the system. The
computer runs this Monitor once per trip. The Secondary Air System
Monitor is a “Two-Trip” monitor. If a fault is found on the first
trip, the computer temporarily saves this fault in its memory as a
Pending Code. The computer does not command the MIL on at this
time. If the fault is sensed again on the second trip, the computer
commands the MIL “On,” and saves the code in its long-term
memory.

2.7 DTCs and MIL StatusWhen the vehicle’s on-board computer
detects a failure in an emissions-related component or system, the
computer’s internal diagnostic program assigns a diagnostic trouble
code (DTC) that points to the system (and subsystem) where the
fault was found. The diagnostic program saves the code in the
computer’s memory. It records a “Freeze Frame” of conditions
present when the fault was found, and lights the Malfunction
Indicator Lamp (MIL). Some faults require detection for two trips
in a row before the MIL is turned on.
Note: The “Malfunction Indicator Lamp” (MIL) is the accepted
term used to describe the lamp on the dashboard that lights to warn
the driver that an emissions-related fault has been found. Some
manufacturers may still call this lamp a “Check Engine” or “Service
Engine Soon” light.
There are two types of DTCs used for emissions-related faults:
Type “A” and Type “B.” Type “A” codes are “One-Trip” codes; Type
“B” DTCs are usually Two-Trip DTCs.When a Type “A” DTC is found on
the First Trip, the following events take place:• The computer
commands the MIL “On” when the failure is first found.• If the
failure causes a severe misfire that may cause damage to the
catalytic converter, the MIL “flashes” once per second. The MIL
continues to flash as long as the condition exists. If the
condition that caused the MIL to flash is no longer present, the
MIL will light “steady” On.
• A DTC is saved in the computer’s memory for later retrieval.•
A “Freeze Frame” of the conditions present in the engine or
emissions
system when the MIL was ordered “On” is saved in the computer’s
memory for later retrieval. This information shows fuel system
status (closed loop or open loop), engine load, coolant
temperature, fuel trim value, MAP vacuum, engine RPM and DTC
priority.
When a Type “B” DTC is found on the First Trip, the following
events take place:
-
LAUNCH 529 OBD II Scanner User’s Manual
17
• The computer sets a Pending DTC, but the MIL is not ordered
“On.” “Freeze Frame” data may or may not be saved at this time
depending on manufacturer. The Pending DTC is saved in the
computer’s memory for later retrieval.
• If the failure is found on the second consecutive trip, the
MIL is ordered “On.” “Freeze Frame” data is saved in the computer’s
memory.
• If the failure is not found on the second Trip, the Pending
DTC is erased from the computer’s memory.
The MIL will stay lit for both Type “A” and Type “B” codes until
one of the following conditions occurs:• If the conditions that
caused the MIL to light are no longer present for the
next three trips in a row, the computer automatically turns the
MIL “Off” if no other emissions-related faults are present.
However, the DTCs remain in the computer’s memory as a history code
for 40 warm-up cycles (80 warm-up cycles for fuel and misfire
faults). The DTCs are automatically erased if the fault that caused
them to be set is not detected again during that period.
• Misfire and fuel system faults require three trips with
“similar conditions” before the MIL is turned “Off.” These are
trips where the engine load, RPM and temperature are similar to the
conditions present when the fault was first found.
Note: After the MIL has been turned off, DTCs and Freeze Frame
data stay in the computer’s memory.
• Erasing the DTCs from the computer’s memory can also turn off
the MIL. If a Diagnostic Tool or Scan Tool is used to erase the
codes, Freeze Frame data will also be erased.
